Bad or destructive caterpillars are species that destroy, the flowers, fruits, leaves, and shoots, while the good or beneficial caterpillars once stages are complete transform into adults and pollinate garden plants. The sad reality is that many offspring (larvae) of butterflies are taken for caterpillars that cause destruction and are killed off however nearly all caterpillars including the good guys eat plants. ” Good caterpillars have limited impact on garden plants and make contributions to our ecosystem.
